Toggle for usage based pricing instead of fast requests

Right now max models use up available fast requests (and as I understand it afterwards all requests max or non max will use usage based pricing). What I would like is a toggle so I could choose if max models will use fast requests or usage based pricing, as it was before. Because right now each max prompt costs me around 20 fast requests and that way I will run out very quick and have to pay for all requests, even non max, if I understand correctly.
